Nonspecific low back pain (LBP) has been defined as tension, soreness, or stiffness in the lower back region, the specific cause of which is unidentifiable.1 This systematic review and meta-analysis provides a rigorous assessment of the effectiveness of osteopathic manipulative treatment (OMT) on nonspecific LBP.

"Randomized clinical studies" (identified by the authors as RCTs) published or unpublished and unrestricted by language were included to remove reservations held from previous studies2-4 and to meet criteria identified by the Cochrane Handbook.5 Criteria for inclusion were RCTs with adult participants with nonspecific LBP for any duration who received OMT techniques on the basis of the clinical judgment of osteopaths or osteopathic physicians. The inclusion criteria identified 307 studies. Further classification identified 15 RCTs comprising a total of 1502 participants and 18 associated comparison groups. Studies were evaluated in 4 areas: (1) acute and chronic nonspecific LBP, (2) chronic nonspecific LBP, and (3) nonspecific LBP in pregnant and (4) postpartum women. Primary outcomes were pain and functional status 3 months after treatment. The GRADE (Grades of Recommendation, Assessment, Development, and Evaluation) system was used to assess the quality of evidence.

Using 10 RCTs, 12 comparison groups, and 1141 participants, OMT was found to have a significant effect on relief of acute and chronic pain (mean difference [MD], –12.91; 95% CI, –20.00 to –5.82). Using 9 RCTs, 10 comparison groups, and 1046 participants, OMT also improved functional status in patients with acute and chronic pain (standardized MD [SMD], –0.36; 95% CI, –0.58 to –0.14). In patients with chronic nonspecific LBP, OMT was found to have a significant effect on pain using 6 RCTs, 7 comparison groups, and 769 participants (MD, –14.93; 95% CI, –25.18 to –4.68), and for functional status using 3 RCTs (SMD, –0.32; 95% CI, –0.58 to –0.07).

The results of this analysis, similar to the findings of Licciardone et al,2 suggest that OMT improves pain and functional status in patients with acute and chronic nonspecific LBP. (doi:10.7556/jaoa.2015.009)
